Seafire,
A few things you left out.....is your Pac-Nor a 3 groove ??? were the 115gr Bergers target or hunting ??? were you really using RL19 or Bluedot ??? how many rounds down the barrel ???
No Blue Dot, not a 3 grove, yes using it for target so far with 115s... use 75 grain HP Hornadys for varminting... why do you think I use
Blue Dot in everything all the time??... rifle has about 1800 or so rounds down the barrel according to log notes....
any more questions sarcastically burning a hole in your head I can answer for ya?
